Requires modifying the electrical system.

Full official abstract

This amendment adopts a new airworthiness directive (AD) for Bell Helicopter Textron Canada (BHTC) Model 430 helicopters that requires modifying the electrical system. This amendment is prompted by the loss of electrical power due to design deficiencies discovered during single-pilot Instrument Flight Rules (IFR) flight testing. The actions specified by this AD are intended to prevent loss of electrical power and subsequent loss of control of the helicopter.
